We are pleased to announce the seventh AIMMS/MOPTA Optimization Modeling Competition. The competition is jointly organized by the conference organizers of MOPTA and AIMMS. Finalists are expected to attend and present their results at the 2015 MOPTA Conference to be held July 20-22, 2015 at Lehigh University, Bethlehem, PA, USA.

Problem Description

This year’s challenge will be on Project Portfolio Management. Large companies address grand challenges by completing a multitude of projects. For instance, developing an innovative new product may require completing dozens of projects, possibly spanning several phases. Companies are likely to develop several new products at the same time, given the risk of delays or failures on each project, and the need to adapt products to an ever changing marketplace.

In the present case, the goal is to assist management with the selection of projects to pursue, over a three-year horizon, subject to risk constraints. Problem solutions can be developed using the free AIMMS Academic License. Click here to download the full problem description. To register, please visit the MOPTA website.

Team eligibility

Teams of at most three students can participate. The team leader has to be a graduate student, though the other members of the team can be advanced undergraduate students. Each member of the team must be registered as a full-time student at a recognized educational institution during the Spring term of the 2014-2015 academic year. Students with a background in optimization, regardless of their actual field of study, are eligible. Collaboration between students from different departments is strongly encouraged. Each team must declare a team advisor with which the team may consult about the problem and their solution. It is the team advisor’s responsibility to ensure that the students have appropriate knowledge for the competition. The team advisor should not be involved as a participant in the solution process.

Last year’s winning team


Team Coppta and Senior AIMMS and Optimization Specialist Peter Nieuwesteeg

In 2014, team Coppta from Universidad de los Andes (University of the Andes) in Colombia won the AIMMS-MOPTA modeling competition. The team, consisting of Daniel M. Eslava, Jorge A. Huertas, Andrés F. Pardo and their advisor Jaime E. Gonzalez , was chosen as winner out of three finalists.

Their challenge was to create a decision support tool that would help the government in a small borough set the price of electricity for both residents and industries. One of the key tasks was to model consumer behavior when the price of electricity changes. The winning team created an iterative and heuristic approach to the bi-level optimization problem, combined with an elegant AIMMS application that could be used by the government. The winners, as well as the other teams, offered a good example of how optimization can help decision makers tackle challenging problems.

We encourage you to visit our competition overview page to learn more about this and other success stories.

About the conference

MOPTA aims at bringing together a diverse group of people from both discrete and continuous optimization, working on both theoretical and applied aspects. There will be a small number of invited talks from distinguished speakers and contributed talks, spread over three days. The conference’s target is to present a diverse set of exciting new developments from different optimization areas while at the same time providing a setting which will allow increased interaction among the participants. Fostering interaction between researchers from both the theoretical and applied communities is the ultimate goal of the event. AIMMS is proud to be one of the conference’s key sponsors.
